VALVE.

Specification of Letters Patent.

Patented May 10, 191d.

App1ication filed June 5, 1909. Serial No. 500,318.

To all whom it may concern:

Be it known that I, CHAnLns E. STRONG, a citizen of the United States,residing at Amityville, in the county of Suffolk and State of New York,have invented certain new and useful Improvements in Valves; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to improvements in valves, and particularly towhat are known as rubber valves, and has for an object the arrangementof means in a valve for rotating the valve automatically by the actionof the fluid passing therethrough.

Another object of the invention is the arrangement of a valve havingprojecting members arranged at an angle to the flow of fluid through thevalve, so that upon the opening of the valve and the closing of the samethe fluid flowing therethrough will partially rotate the valve.

A still further object of the invention is the arrangement of a rubbervalve member adapted to be moved from its seat upon the passage of fluidthrough the valve, said valve member being formed with projections thatare beveled or have formed thereon inclined surfaces against which thefluid passing through the valve acts for giving a rotary motion to thevalve member as the same moves off its seat and again back upon itsseat.

IVith these and other objects in view the invention comprises certainnovel constructions, combinations and arrangement of parts as will behereinafter more fully described and claimed.

In the accompanying drawings: Figure 1 is a side elevation of a pump,certain parts being broken away to disclose the invention. Fig. 2 is atop plan view of a valve member removed. Fig. 3 is an edge view of thevalve member shown in Fig. 2. Fig. 4 is a top plan View of a slightlymodified form of valve member. Fig. 5 is an edge view of the structureshown in Fig. 4.

In the construction of valves, and particularly to what are known asrubber pump valves, the rubber valve member arranged in the valve isforced from its seat upon each pulsation of the pump, and againreseated. This unseating and reseating of the valve member will ofcourse wear the same in the joint.

course of time, especially as the valve member is reseated in the sameplace each time. After the valve member has been used for some time ithas often been found that the grooves or worn places in the valve memberwill be engaged by the fluid passing through the valve, and the valvemember slightly rotated. This slight rotation of the valve member willcause the same to leak as the same is not seated in the worn places, andconsequently is held from forming a tight In the valve embodying theinvention means are presented for overcoming this objection as the valvemember is adapted to be continuously and automatically rotated forwearing the same evenly, and thus preventing any leaking by being seatedupon a rough place.

Referring to the drawing by numerals, 1

indicates a pump of any desired kind, in

which is arranged a valve 2 having a valve member 3 adaptedto engage itsseat 4 when not raised by the pressure of fluid passing therethrough.The valve member 3, as more clearly shown in Figs. 2 and 3, is formed ofa disk having an aperture 5 for permitting the passage of a guiding rodtherethrough. Secured to or formed integral with disk 3 are a pluralityof projections 6 that are curved at 7 and 8, preferably in substantiallya compound-curve, on opposite sides of the projections. By thisconstruction and arrangement blades are formed on the disk against whichthe fluid may press for rotating the disk whenever the disk is not heldagainst rotation. By having the curved surfaces 7 and 8 as shown eitherside of the valve member 3 may be placed against the seat and the fluidpassing through the valve will operate equally upon the projections orblades 6 for rotating the valve member. The valve member 3 may be madeof any desired material, but preferably of rubber, and is particularlyadapted to be used in what is known as rubber pump valves.

In Figs. 4 and 5 will be seen a slightly modified form of theinvent-ion, in which a valve member 3 is provided with projec tions 6having curved surfaces 9 and 10 upon opposite sides of the projections6. Projections 6 also have straight surfaces 11 and 12. The curvedsurfaces 9 and 10 are adapted to be engaged by fluid passing through thevalve, whereby the valve memher 3 is rotated. By providing the curvedsurfaces 9 and 10 in the modified form, and

the curved surfaces 7 and 8 in the preferred form, the valve member maybe reversed or put on either side down, as desired, and operate withequal advantage. By the use of the disk arrangement of valve members 3and 8, and the lugs, arms or Wings 6 and 6,

means are provided for presenting an efl'i cient valve member, and onethat in operation Will move forward in a rotary motion upon eachpulsation.

What I claim is:

1. In a valve, a reciprocating valve member, peripheral arms projectingfrom said valve member formed substantially in the shapeof a compoundcurve having a part of the sides thereof flattened at diagonal cornersfor causing the valve member to rotate upon the passage of fluid throughthe valve. 2. In a valve, a valve member formed substantiallydisk-shaped, and arms arranged on the periphery thereof, extendingsubstantially in a general direction parallel with the axis of the valvemember and formed with Walls having diagonal rounded corners and merginginto diagonal flattened corners.

8. In a valve, a valve member formed sub stantially disk-shaped, and aplurality of arms each formed with a plurality of curved surfacesarranged to be acted upon by fluid passing through thevalve for rotatingthe same in one direction regardless of which side of the valve memberis uppermost, each of said arms being arranged substantially parallel tothe axis of the valve member and located upon the periphery thereof.

l. In a valve, a disk shaped valve member, a plurality of arms arrangedon the periphery thereof formed with beveled surfaces upon oppositesides and arranged in opposition to each other, whereby the arms mayengage the "fluid passing through the valve, regardless of which side ofthe valve member is uppermost.

5. In a valve, a reciprocating (llSk-SlltlPQtl valve member formed withspaced peripheral arms, each of said arms extending in a generaldirection parallel with the axis of the valve member and formed withdiagonal corners rounded in order to cause the valve member to partiallyrotate upon each unseating thereof regardless of which side isuppermost.

In testimony whereof I aflix my signature in presence of two witnesses.
